We frequently get questions such as these:

"What is energy?"

"What are Cooper Pairs?"

"What is conservation of momentum?"

etc...etc.

And the persons who asked such questions didn't bother to explain the context of the question, what exactly did he/she wanted to know, and didn't reveal the level of education that he/she could understand.

While we welcome questions, in this day and...

We make great effort to ensure that HW/Coursework-type posts are placed in the HW/Coursework forum. We also make great effort in ensuring that every member would not miss this requirement. We made three different notices to draw everyone's attention to this requirement:

1. It is plainly stated in the PF Rules that everyone had agreed to.

2. In the physics forums, we have posted Sticky thread with the blatant title "Do Not Post Your HW Here". Can't get any...

Actually, if you're expecting an answer to that question, you'll be sorta disappointed. I won't answer it here.

But after coming across ANOTHER thread asking "What is energy?", I kinda sigh and then wondered if this is the question most often asked on PF. It might be. I did a quick search and found these thread asking for the same thing:

During my participation on PF (which has been quite a number of years already), I've seen a couple of incarnations of this particular forum. It was called "Theory Development" when I first joined. Then, it became "Independent Research" forum. Whatever it is called, it was one way PF is trying to do two things:

1. to provide a forum for someone to present/work out his/her own personal theory and ideas, and

2. to prevent such a topic from being in...

"I heard that...", "I read somewhere that...", "I was told that... ", "I saw on TV that..."

We get a lot of those types of starting statement here on PF. Members want us to explain, discuss, correct, corroborate, debunk, etc. stuff that they've come across in one form or another.

Now, unless the source cited is well known (i.e. "I saw on TV from "Elegant Universe"..."), then inevitably, the source that these...
